Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456462, here are decompositions:

83 + 31456379 = 31456462
101 + 31456361 = 31456462
131 + 31456331 = 31456462
263 + 31456199 = 31456462
269 + 31456193 = 31456462
383 + 31456079 = 31456462
449 + 31456013 = 31456462
503 + 31455959 = 31456462

Showing the first eight; more decompositions exist.
